Timer Period
This field is used in the equation to configure SCL_PERIOD:
SCL_PERIOD = 2×(1 + TPR)×(SCL_LP + SCL_HP)×CLK_PRD
where:
SCL_PRD is the SCL line period (I
2
C clock).
TPR is the Timer Period register value (range of 1 to 127).
SCL_LP is the SCL Low period (fixed at 6).
SCL_HP is the SCL High period (fixed at 4).
CLK_PRD is the system clock period in ns.
